Composition and structure of a lowland forest in the core zone of the Bukit Duabelas National Park, Jambi, Indonesia

The objective of the study was to obtain data on composition and structure of the forest in the midsection of the Bukit Duabelas National Park core zone, designed to complement the existing data and  provide new information  potentials for the management of the park  core zone. The study was carried out in October-November 2012. Observations were made on plots of one hectare (100 m x 100 m), which was divided into 100 subplot, measuring 10 m x 10 m each. Enumeration  of tree species with  diameters ≥ 10 cm revealed that as many as 540 individuals were recorded, consisting of 89 species and 36 families, with a total  basal area of 30.837 m2 and  only three species of Dipterocarpaceae were registered. The forest had a low diversity as indicated by low species richness, much lower than in the  undisturbed lowland  primary forests in the Batang Gadis National Park in North Sumatra, where similarity was very low (5.9 %).  The forest in the plot was designated as the  Dacryodes rostrata- Shorea leprosula Association,  named after two species with highest importance values, thus the dominant. The structure and species composition pointed to the regenerating  forest after heavy disturbances.  The forest has been  undergoing  slow natural succession,  leading to  the formation of the forest similar to the original climax forest. Natural recovery through succession could be enhanced and assisted by means of ecological restoration, through planting of tree species characteristics of forests in Jambi, including  species of Dipterocapaceae, useful species having values to maintain the livelihood of the indigenous native tribe Suku Anak Dalam  and rare, endemic other species having  high conservation values. Tujuan studi  ini adalah  untuk memperoleh data tentang komposisi dan struktur hutan di bagian tengah zona inti Taman Nasional Bukit Duabelas. Studi   dirancang untuk melengkapi data yang telah ada dan untuk menyajikan informasi baru yang berpotensi untuk digunakan dalam pengelolaan zona inti taman nasional. Penelitian dilaksanakan pada bulan Oktober-November 2012 dalam petak seluas satu hektare (100 m x 100 m), yang dibagi menjadi 100 anak-petak dengan ukuran masing-masing 10 m x 10 m.   Pencacahan pohon dengan diameter ≥ 10 cm  menghasilkan 540 batang, yang terdiri atas 89 jenis dan 36 suku, dengan luas bidang dasar total 30.837 m2 dan hanya tercatat  tiga jenis Dipterocarpaceae. Keanekaragaman jenis hutan rendah,  seperti  ditunjukan oleh  rendahnya kekayaan jenis, jauh lebih rendah dibandingkan dengan  hutan primer yang tidak terganggu di Taman Nasional Batang Gadis di Sumatra Utara, yang mempunyai  kesamaan hanya 5,9 % dengan Taman Nasional Bukit Duabelas.  Berdasarkan dua jenis dominan dengan nilai kepentingan tinggi, komunitas pohon dalam petak dinamakan Asosiasi Dacryodes rostrata- Shorea leprosula. Struktur dan komposisi jenis menunjukan status hutan sebagai hutan yang sedang beregenerasi setelah mengalami gangguan. Hutan sedang mengalami suksesi alami yang lambat menuju ke pembentukan hutan yang serupa dengan hutan klimaks aslinya. Pemulihan alami melalui suksesi dapat dipercepat dan dibantu dengan restorasi ekologi melalui penanaman jenis-jenis khas hutan alami Jambi, termasuk  Dipterocapaceae, jenis-jenis bermanfaat dan mempunyai nilai untuk keberlanjutan kehidupan dan kesejahteraan masyarakat asli Suku Anak Dalam dan jenis-jenis langka, endemik dan jenis lain yang mempunyai nilai konservasi tinggi

Ethnoecology of The Slamet Mountain Slope Community (SMSC) in Paguyangan District, Brebes Regency, Central Java

The local communities have local knowledge in utilizing and managing landscape units. The threat of modernization has led to the degradation of local knowledge, including the Javanese community on Mt. Slamet. This study aimed to analyze the plant diversity characteristics of landscape units and determine the important value of landscape units and plant species used by the community. This research was conducted in the Ragatunjung, Cipetung, and Pandansari village, Paguyangan District, Brebes Regency, Central Java. Semi-structured interviews collected Ethnoecological data with eight key informants and 83 respondents selected by purposive sampling and snowball sampling. Data on the level of landscape utilization were analyzed using the Local User's Value Index (LUVI). The community recognizes nine types of landscape units, such as perawisan (yard), wanah (production forest), Majegan (gardens), Sabin (rice fields), Kubang buyut (protected forest plan), tea plantations, Telaga Ranjeng Nature Reserve, Tanah Bengkok and tuk (water sources). Wanah was the most important landscape unit in the community in Ragatunjung (31.27), Cipetung (53.55), and Pandansari (28.17). Oryza sativa had the highest importance value in Sabin (22) and wanah (12) of Ragatunjung. In contrast, Syzygium aromaticum had the highest in Majegan (6.68). Brassica oleracea has the highest importance value in the two landscape units of Cipetung, namely, Majegan (4.20) and settlements (3.5), while in the wanah is Zea mays (11.38). Solanum tuberosum had the highest value in each landscape unit in Pandansari, both in wanah (10.33), Majegan (6.80), and Protection Forest Plan (PFP) (4.13). Categorizing landscapes and their utilization by maintaining certain landscapes, such as the Telaga Ranjeng Nature Reserve and Kubang buyut, directly impact the sustainability and integrity of ecosystems and natural resources in and around the area
